A self-styled sugar daddy who pays cash-strapped students for sex spent £121,000 on champagne last night celebrating a big win at a casino.

Dexter Koh, who owns a public relations company in Shoreditch, claimed he won a six-figure sum in a high-stakes night of gambling before arriving at Aura nightclub in Mayfair at midnight.

By the early hours today, Mr Koh, 30, blew more than £121,000 on champagne, including a single Methuselah of Cristal — six litres — at £26,000.

Mr Koh, who has openly admitted entering into “mutually beneficial arrangements” with university students in return for sex, tweeted photographs from inside the nightclub, surrounded by models and huge champagne bottles fizzing with sparklers.

He highlighted yesterday’s date, writing: “12/12/12 wow just smashed it again on the tables. Six figures. What a way to end the year. Let’s get my drink on!”

Other items on the bill included one Jeroboam of Ace of Spades champagne, three litres, which cost £16,500. He kept his 19,000 Twitter followers updated through the night, adding tweets including: “having it large”, “this bill will be epic” and “now that’s what I call getting your round in!”.

The flamboyant businessman has been compared to Christian Grey, a central character from the hit “mummy porn” novel Fifty Shades of Grey, who also enters into contractual sexual relationships.

A spokesman for seekingarrangement.com — known as a “sugar daddy” dating site — said:"They show him a good time and he lavishes them with
riches."

Mr Koh recently told how he dated a 24-year-old Bristol University graduate who had student debts of £62,000 and was struggling to find work in London.

He said: “There was no way she could have survived financially without the help of a sugar daddy.

“I really felt sorry for her, she was worried sick about her debt. I really don’t know how some students cope without having very rich parents

“She had dated several sugar daddies before me. She was totally unapologetic about it and admitted that once she had got her career and her finances sorted she would quit the site.”
